Chapter 1557: Truth Heavenly Domain 　

The purple godly stone was taken from Lord Lingquan. Zhang Ruochen had studied it for a long time without figuring out its nature. He only sensed that it contained strong divine power inside.

It was extremely hard. Even the Abyss Ancient Sword couldn't leave a mark on it.

According to Lord Lingquan, it was a purple star collected near a black hole and a weapon saint master produced this stone.

But Ling Xiu seemed to discover something else.

"Senior, do you know what this is?" Zhang Ruochen asked.

Ling Xiu's eyes were a bit solemn. Nodding, he said, "It's related to the Stone Race, one of the three races of Hell World. If I guess correctly, this should be part of a Stone Race's god and…a very important part too."

"Is this like a divine bone?" Zhang Ruochen asked.
